Returning "SUCCESS" is not always enough. Graphics adapter option roms normally
use the PCI bios(int 1a) services to find the card they're attached to and some
stuff similar to that. But as always, the idea is simple, the solution is not.
For safe operation all other graphics adaptors should be hidden during
initialization iirc, according to Egbert Eich from the XFree team.
scitech's x86emu has some examples how that can be done in v86 mode and with
a seperate x86 emulator.
